Hibiscus rosa-sinensis plant named ‘Hollywood’

ABSTRACT

A new and distinct cultivar of  Hibiscus  plant named ‘Hollywood’, characterized by a large ruffled flower with a red center, transitioning to orange with yellow edges, and metallic silver veining evident in the red and orange areas. ‘Hollywood’ is a free flowering plant with an upright, compact habit, and glossy, dark green foliage.

Botanical classification: Hibiscus rosa-sinensis L.

Varietal denomination: The new plant has the varietal denomination ‘Hollywood’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis and hereinafter referred to by the cultivar name ‘Hollywood’.

The genus Hibiscus comprises about 250 species of herbs, shrubs and trees in warm temperate and tropical regions; with leaves usually simple, mostly palmately veined, lobed or parted; flowers are mostly solitary in the leaf axils but sometimes in racemes, corymbs or panicles. Hibiscus is included in the family Malvaceae, which comprises about 95 genera of herbs, shrubs and trees originating in tropical and temperate regions. Hibiscus rosa-sinensis is a glabrate shrub, seldom over 8 feet tall in cultivation, but treelike to 15 feet or more in tropical regions. Leaves grow to 6-inches in length, and are ovate, usually serrate, mostly glossy green. Flowers are solitary in upper leaf axils.

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Webster, Tex. The objective of the program was to create new Hibiscus selections with improved bloom quality, color and floriferousness. A further objective was to produce plants that can be commercially produced on their own root systems, with improved plant habit, with regard to vigor and postproduction longevity.

The new variety was discovered in a controlled breeding program of Hibiscus rosa-sinensis and differs from its parents and other known cultivars of Hibiscus rosa-sinensis by the following characteristics in combination:

-   -   1. Upright, compact symmetrical plant habit that is suitable for         container production;     -   2. Healthy dark green foliage;     -   3. Vigorous growth habit;     -   4. Large ruffled flower with a red center, transitioning to         orange with yellow edges. Metallic silvery veining is evident in         the red to orange zones; and     -   5. Free flowering.

SUMMARY OF THE INVENTION

The cultivar ‘Hollywood’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, nutrition and water status without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Hollywood’. These characteristics in combination distinguish ‘Hollywood’ as a new and distinct cultivar:

-   -   1. Upright, compact symmetrical plant habit that is suitable for         container production     -   2. Healthy dark green foliage.     -   3. Vigorous growth habit.     -   4. Large ruffled flower with a red center, transitioning to         orange with yellow edges. Metallic silvery veining is evident in         the red to orange zones.     -   5. Free flowering.

Asexual reproduction of the new variety by stem cuttings, performed in Webster, Tex. and Houston, Tex., have confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations, and the new variety reproduces true to type.

COMPARISON WITH PARENTS AND OTHER CULTIVARS

‘Hollywood’ is distinguished from its female parent ‘Georgia's Pearl’ (not patented) by its plant habit: ‘Georgia's Pearl’ is taller, with less branching. ‘Hollywood’ is distinguished from its male parent ‘Jason Blue’ (not patented) in the flower color: ‘Jason Blue’ has an orange yellow flower with a silvery blue eye, while ‘Hollywood’ has a flower with a red center, transitioning to orange with yellow edges.

The closest commercial cultivar to ‘Hollywood’ known by the Inventor is ‘Georgia's Pearl’. However, in side-by-side comparisons conducted in Webster, Tex., plants of ‘Hollywood’ differ from plants of ‘Georgia's Pearl’ in the following characteristics:

-   -   1. Flowers of the new Hibiscus have a different color pattern         than flowers of the cultivar ‘Georgia's Pearl’;     -   2. Plants of the new Hibiscus are easier to clone via rooting         than plants of the cultivar Georgia's Pearl; and     -   3. Plants of the new Hibiscus are more compact, with a better         branching habit, than the cultivar ‘Georgia's Pearl’.

‘Hollywood’ also has a sibling, namely the Hibiscus rosa-sinensis ‘Enlightenment’ (U.S. Plant patent application Ser. No. 11/207,517). Although these plants are closely related, they both have distinctive flower coloration. Specifically, the two flowers differ in the following ways:

-   -   1. ‘Hollywood’ has a red center, ‘Enlightenment’ does not;     -   2. The dominant colors on ‘Hollywood's’ flower are red, orange         and yellow, and for ‘Enlightenment’ it is pink, orange and         yellow; and     -   3. ‘Hollywood’ has silver veining transitioning from the red         center into the orange while ‘Enlightenment’ does not.
